In this work, two mononuclear four-coordinate complexes of Ni(II) and Cu(II), formulated as (HNEt3)2[Ni(L)2] (1) and (HNEt3)2[Cu(L)2]·H2O (2) (H2L = N,N′-bis(p-toluenesulfony1)oxamide), have been synthesized and characterized. These complexes are coordinated by two doubly deprotonated oxamide ligands. The crystal structures of both complexes were determined using single-crystal X-ray diffraction, revealing
在这项工作中,Ni(II) 和 Cu(II) 的两个单核四配位配合物,公式为 (HNEt3)2[Ni(L)2] (1) 和 (HNEt3)2[Cu(L)2]· H2O (2) (H2L = N,N'-双(对甲苯磺酰基1)草酰胺)已被合成并表征。这些配合物由两个双去质子化草酰胺配体配位。使用单晶 X 射线衍射确定了两种配合物的晶体结构,揭示了中心金属离子周围高度不规则的配位几何形状。配合物1表现出更接近四面体构型的结构,而配合物2则采用更接近跷跷板构型的结构。直流 (dc) 磁数据表明 1 具有易平面各向异性,零场分裂 (ZFS) 参数 D 的值很大,为 +66.3 cm−1。
